Chamber Kilns/Standard Equipment N 100 - N 660/H
Elements mounted on support tubes give free radiation of heat, longer element and wall life; optimized element positioning for excellent temperature uniformity.
Solid-state relays control the kiln heating. Operating silently and nearly wear-resistant, the solid-state relays switch with short pulses, giving excellent temperature uniformity and fast response times.
Easy-to-use Nabertherm controller, precise temperature regulation.
Flue in the center-rear section of the ceiling ensures uniform flow of exhaust gasses (roof flap for N 440 and N 660).
Handy quick-release locking wheel, door can be secured with padlock.
Dual shell housing for “Cool-Touch” outer surface with side panels made of textured stainless steel (N 100/G N 300/H).
Base for ergonomic loading height included in delivery. Special height or running on casters as additional equipment.
Infinitely adjustable air-inlet damper for optimum air supply during firing and reduced cooling time. Automatic control available as additional equipment.
Large, ergonomic door handle.
Silicon carbide plate protects the bottom heating elements. It is easily removed to permit convenient cleaning of the furnace bottom and element maintenance.
We recommend: To achieve a long service life of the brick lining and heating elements, the kiln should not be fired every cycle at its maximum rated temperature. Up to 1230 °C we recommend models N 100 - N 660, and for regular high firing temperatures above 1230 °C we recommend our models N 100/H - N 660/H.
Accessories Manual Zone Control In combination with the bottom heating, the optional P 310 controller can manually control a second heating zone. As usual, you set the firing profile on the controller. If you determine that the temperature uniformity has to be changed from top to bottom, then you can easily make adjustments of this ratio.
T2 T1 time min
Automatic Air-Inlet Damper After the chemically bound water has been expelled from the ceramics during firing (max. 600 째C), the air-inlet damper on the kiln must be closed to prevent drafts and to ensure good temperature uniformity in the upper temperature range. Nabertherm chamber kilns are generally equipped with adjustable air-inlet dampers. We alternatively offer you an electrical drive for the air-inlet dampers with fully automated control via the C 280 or P 300 controller as initial installation. If your furnace is equipped with a B 130 or another controller without extra function for damper activation, a semiautomatic air-inlet damper controlled via timer can alternatively be used. Electromagnetic closing of the damper occurs after the preset time has elapsed. Retrofitting with this semiautomatic solution is also possible.
Base in special height or on casters.
Loading rack for chamber furnaces. The entire kiln load may be ergonomically inserted or extracted in one movement using a pallet lift truck (N 150 ff). This allows the kiln to be fired again more quickly.
Batts, plates and posts. Matching sets of kiln furniture are available for every type of furnace.
If you have a question, do not hesitate to ask us!
Installation Service Nabertherm and your dealer can help arrange professional installation and assembly of your kiln into your studio. All of our kilns ship completely assembled in one piece. While other manufacturers sell sectional designs, we do not because it negatively affects the performance and safety of our kilns. A one-piece design may take more effort on the day you install your kiln, but its effortless operation every day thereafter more than makes up for this.

Gas-heated Chamber Kilns
NB 600 NB 300 with base frame
NB 300 - NB 600 Some firing processes require a gas-heated chamber kiln. Fast heating times and unique firing results are strong reasons for using such equipment. Equipped with powerful gas burners the chamber kilns NB 300 - NB 600 are suitable for many creative applications. Temperature regulation included in the basic model The controller starts controlling after the burner has been manually ignited by automatically switching the burner between high and low loads. The burners have been optimized to allow relatively precise control from 300 °C. Despite this, we still recommend drying the charge completely to avoid waste caused by rapid warming in the lower temperature range. At the end of the program, the burners are automatically shut off.
